DatabricksPooledConnection

public DatabricksPooledConnection(Connection physicalConnection)

Creates a new PooledConnection representing the specified physical connection.

Parameters:

physicalConnection - connection

Method Detail

addConnectionEventListener

public void addConnectionEventListener(ConnectionEventListener connectionEventListener)

Specified by:

addConnectionEventListener in interface PooledConnection

removeConnectionEventListener

public void removeConnectionEventListener(ConnectionEventListener connectionEventListener)

Specified by:

removeConnectionEventListener in interface PooledConnection

removeStatementEventListener

public void removeStatementEventListener(StatementEventListener listener)

Specified by:

removeStatementEventListener in interface PooledConnection

addStatementEventListener

public void addStatementEventListener(StatementEventListener listener)

Specified by:

addStatementEventListener in interface PooledConnection

close

public void close()
           throws SQLException

Close the physical connection once the pooled connection is closed

Specified by:

close in interface PooledConnection

Throws:

SQLException

getConnection

public Connection getConnection()
                         throws SQLException

Gets a handle for a client to use. This is a wrapper around the physical connection, so the client can call close, and it will just return the connection to the pool without really closing the physical connection.

According to the JDBC 4.3 Optional Package spec (11.4), only one client may have an active handle to the connection at a time, so if there is a previous handle active when this is called, the previous one is forcibly closed.

Specified by:

getConnection in interface PooledConnection

Throws:

SQLException

getPhysicalConnection

public Connection getPhysicalConnection()
